Abstract
Un inhibidor de vórtice para separar escoria de metal fundido durante la descarga de metal fundido a través de una buza de colada incluye un cuerpo refractario moldeable uniforme con una forma generalmente ahusada, una cámara hueca adentro del cuerpo y un miembro de sacrificio alargado. La cámara hueca recibe al miembro de sacrificio o un montaje para el miembro de sacrifico. La combinación de cuerpo refractario y miembro de sacrificio en metal fundido tiene una gravedad específica menor que la gravedad específica del metal fundida y se posiciona con el extremo angosto hacia abajo cuando está soportada en metal fundido. La cámara hueca puede llenarse con metal fundido para formar un núcleo que ayuda a orientar el cuerpo de una posición hacia abajo de extremo angosto. El miembro de sacrificio se alinea con el área en la cual se forma el vórtice y minimiza la interferencia con el flujo a través de la buza de colada. Preferiblemente el cuerpo incluye superficies que obstruyen el torbellino.A vortex inhibitor for separating molten metal slag during the discharge of molten metal through a casting bushing includes a uniform moldable refractory body with a generally tapered shape, a hollow chamber inside the body and an elongated sacrificial member. The hollow chamber receives the sacrificial member or a mounting for the sacrificial member. The combination of refractory body and slaughter member in molten metal has a specific gravity less than the specific gravity of the molten metal and is positioned with the narrow end down when supported in molten metal. The hollow chamber can be filled with molten metal to form a core that helps orient the body from a downward position of narrow end. The sacrificial member aligns with the area in which the vortex is formed and minimizes interference with the flow through the casting bucket. Preferably the body includes surfaces that obstruct the whirlpool.
